Osmosis Lab Reports Diffusion is the random movement of molecules from an area of high concentration to an area of lower concentration. From diffusion, the process of osmosis is found. Osmosis is a special case of diffusion. In osmosis, the diffusion of water through a selectively permeable membrane occurs. This diffusion is a movement from a region of higher water potential to a region of lower water potential. Here water potential is the measure of …showed first 75 words of 272 total…

In the third experiment, I hypothesize that the dialysis bag of 1M and 2M sucrose will increase in height, which is placed in a beaker of distilled water.
